WATER-SEAL TRAP.

SPECIFICATION forming part of Letters Patent N o. 683,884, dated October 1, 1901.

Application filed August 30, 1 900. Serial No. 28,519. (No model.)

p prevent sewer and other noxious gases from passing into the at-mosphere from a sewer connected thereto.

Traps such as are commonly used to seal waste-pipes by means of water are liable at times to become clogged by foreign Vmatters entering the Waste-pipes and which'by adhering to the walls thereof gradually reduce Similar numerals indicate similar parts inv the several views.

l indicates the inlet end or pipe of a trap constructed in accordance with myinvention.

2 represents the outlet, and 3 the connecting or water-seal portion between the two ends, it being curved downwardly in the usual manner. A pipe 4 extends in a substantially horizontal direction from the point of connection between the parts 2 and 3 to and through the inlet-pipe 1. The pipe 4 is practically the 'same diameter 'as the other parts of the trap except where it passes through the inlet-pipe, `the diameter therel being reduced, as at 5. `The inlet-pipe l is enlarged at that part 10 through which the pipe 4 passes, this being necessary to afford suicieut space for the passage of water Varound the said pipe.

partv 5 is provided with a screw-plug 7, a

`similar one 9 being also placed at the lower The outer end of the outlet-pipe, Which'latter maybe horizontal or it may curve downwardly, as shown by the dotted lines in Fig. `2: A flexible rod of metal, wood, ratan, or other substance may be readily introduced through the pipe f1 and the obstruction broken down and withdrawn.

I have hereinabovel described my invention as applicable to washbasins and other ,K

places where a trap' of small size is needed. It is, however, adapted to traps of larger size-such, for instance, as water-closet traps,

draintraps, dac. The trap is preferably made of one piece, either cast or molded of earthenware, although it may be made ot more than one piece and soldered when made of. A

lead. The parts 4 and 5 may and preferably will be of relatively smaller dimensions in large traps, the passage through said parts requiring to be of suchsize as to admit of the sof introduction of the necessary cleaning implev ments.

Having thus described my invention, I

1. A trap with a water seal having a passage open to the air extending from the highest part of the waste-pipe and in line therewith and with the Water seal to and through.

the inlet-pipe, and a plug to closethe outer end of the passage, substantially as set forth.

3. Ina trap, the combination of an'inlet-L e pipe, an outlet-pipe, and a water sealconnect- Y pipe, and a water seal between the two pipes,

ICO'

a straight passage extending from the j unction of the outlet-pipe and Water seal and in line therewith to and through the enlarged portion of the inlet-pipe, substantially as set forth.

5. In a trap, the combination of an inletpipe having an enlarged portion, an outletpipe, a Water seal between the two pipes, a straight passage extending from the junction of the Waste-pipe and Water seal and in line therewith to and through the enlarged portion of the inlet-pipe, that part of the passage passing through the Vinlet-pipe being of less diameter than the remaining part, and a plug to close the passage, substantially as set forth.

6. In a trap, the combination of an inletpipe having an enlarged portion, an outletpipe, a U-shaped water seal between the two pipes, a straight passage extending from the junction of the waste-pipe and Water seal to junction of the Waste-pipe and water seal to and through the enlarged portion of the in1etpipe, that part of the passage passing through the inlet-pipe being of less diameter than the remaining part, and a plug to close the passage, substantially as set forth.

. In testimony whereof I hereunto set my hand and seal.
